Recloseable lid for a container for powdered chemicals and the like

ABSTRACT

One of the sidewalls of a rectangular container has a double layer of inner and outer walls. The upper portion of the outer wall is bent and extended beneath the inside of a top wall and pasted thereto. The upper side portions of the outer wall are provided with a notched line. Also the end portions of the top wall near said double layer are provided with notched lines. By severing and opening said notched line and lines, the lid of a container for powdered chemicals and the like can be opened. And even after its lid has been opened, it is maintainable in its closed condition by inserting the tongue into behind said double layer.

Y mmlmmal Mimi ATTORNEY s RECLOSEABLE am FOR A CGNTAINELR FOR PQ'WDEEED(JHEMHCALS AND THE LHKlE This invention relates to a recloseable lid ofa container for powdered chemicals and the like. An object of thisinvention is to provide a container which enables its user to open itslid initially by only pulling the device lightly with his fingers.Another object of this invention is to provide a container which ismaintainable in its closed condition even after its lid has been opened,and which is also able to prevent spillage of its contents in the eventit falls down after its lid has been initially opened and reclosed.

l-leretofore the known type of container for cleanser and other powderedchemicals usually had such a construction that both of its sidewalls hadonly a single layer and not a double layer, wherein the upper portion ofone of the sidewalls was provided with a tonge-shaped notched line, andthat the ends of its top wall were provided with notched lines, each ofwhich was continuous with said tonge-shaped line. In opening of suchknown containers said tongue-shaped portion was psh pushed, and thenotched lines were severed and opened, forming an open mouth along theupper portion of the sidewall and the portions of the top wall, and itscontents were pourables pourable out of the open mouth. Thus, it couldaccomplish the purpose of opening the lid. In opening it, however, thelid was ps pushed inwardly and severed. Thus, it had a disadvantge thatits operation was difficult and smooth pouring of the contents was oftenprecluded by the lid being bent inwardly. Furthermore, when its lid wasonce opened, it could not be closed tightly again, because its openingwas effected by practically breaking the lid. Thus, when it was onceopened, it was left as it was, and in the event it fell down, theremainder of its contents was split. Thus, it had a disadvantage that ittended to waste its contents and stain a floor when it fell down.

The container of this invention removes such disadvantages. In openingit, an edge of a tongue is held between its users fingers and pulledoutwardly. Then, notched lines are severed and the lid is opened. Thismethod is much simpler than the conventional method. What is more, evenafter its lid has been opened, its lid can be easily closed by insertingthe tongue from the upper portion of an inner wall of a sidewallsomewhere behind or inside of the inner wall, as shown in FIG. 3.Therefore, in the event that the container falls down, the remainder ofits contents will not be spilt. Unlike the conventional container, itdoes not have the disadvantage of wasting its contents or staining afloor.

In the accompanying drawings:

FIG. 1 is a perspective view of apparatus embodying this invention whenit is in its manufactured closed condition, and before it is initiallyopened;

FIG. 2 is a perspective view of the same when it is initially opened;

FIG. 3 is a sectional view of principal parts when apparatus embodyingthis invention is closed again;

FIG. 4 is a perspective view of the apparatus embodying this inventionwhen it is reclosed;

FIG. 5 is a developmental view of the carton or container blank.

Referring now to the drawings which show one embodiment of thisinvention, an end wall 1 on the opening side of a container has adoubler layer of inner and outer walls a and b. An extension 0 isintegral with the outer wall b and is extended from the upper edgethereof and is bent and inserted beneath a lower top wall 2 and pastedthereto. The upper end portions a' of the outer wall b are demarcated bya tongue e. The left and right sides of the body m of the tongue e arenotched along lines f and g. An edge I of said tongue e is separatedfrom the outer wall b by a cut I: so as to be picked up. A fold i isplaced between the body m and the edge lof the tongue e.

Upper portions of a front wall 3 and a rear wall l are extendedrespectively as wide as the width of the top wall through means of folds6 and 7. Such extensions are designated as an upper wall 8 and the lowertop wall 9 respectively. The lower top wall 9 is placed just beneath theupper I top wall 8 and pasted together to form a tightly closed top wall2. Notches j and k are made along portions of said folds 6 and 7 nearthe sidewall l.'The numeral 5 designates an openable portion of theupper top'wall 8. The openable portion fi projects slightly at 6' (FIG.5) to cover the upper portion of the inner wall a.The numeral 10designate a paste covered portion of the lower top wall 9 near thesidewall I. Said paste covered portion 10 is extended through a fold illand serves to paste the outer surface of the tongue e and the uppersurface of the extension c together.

The device of this invention has such a construction as has beendescribed above. In opening the lid of a container, the tongue I is notpressed in an inward direction. The edge [of the tongue e is so arrangedas to be picked up independently of the body m by means of the fold i.In opening it, therefore, the edge I of the tongue e is held between itsusers fingers and pulled. Then, the notched lines f, g, j and k areeasily severed so as to open the tongue e and the lid member 5 outwardlyand upwardly. Thus, the opening operation of the container of thisinvention is much easier than that of the conventional container, andthe container of this invention has remarkable advantages. What is more,as the end wall 1 is also provided with the inner wall a, the end wall Idoes not open even after the lid member 5 and the tongue e have beenopened. Thus, only the top wall is opened with the inner wall beingclosed. If, therefore, the edge I of said tongue 2 is inserted somewhereinside the upper portion of said inner wall a, as shown in FIG. 3, theopen portion of the top wall 2 is easily placed in a closed condition.Even if the container of this invention falls or is dropped while it isbeing handled, powdered chemicals which are in it will not be spilled,and the container will maintain in its closed condition.

Besides, the openable portion 5 of the top wall 2 is provided with aprojection 6' which juts out slightly to cover the upper portion of theinner wall a. Thus, when the tongue e is inserted into the inner wall a,the said projection 6' prevents the said tongue e from being hiddentherein, and the container can maintain in its closed condition in anorderly manner.
